[jira] [Created] (HIVE-23741) Store CacheTags in the file cache level

Antal Sinkovits created HIVE-23741:
--------------------------------------

             Summary: Store CacheTags in the file cache level
                 Key: HIVE-23741
                 URL: https://issues.apache.org/jira/browse/HIVE-23741
             Project: Hive
          Issue Type: Improvement
            Reporter: Antal Sinkovits
            Assignee: Antal Sinkovits


CacheTags are currently stored for every data buffer. The strings are internalized, but the number of cache tag objects can be reduced by moving them to the file cache level, and back referencing them.
